6.7GHz 80 MHz Bandwidth Psa Series Spectrum Analyzer Agilent E4443A

The pre-owned Agilent E4443A PSA delivers high-performance spectrum analysis from 3 Hz to 6.7 GHz with a fully digital IF and up to 80 MHz instantaneous bandwidth—ample for 5G FR1, WLAN, and radar bursts.

A –118 dBc/Hz phase-noise floor and –155 dBm/Hz DANL expose low-level spurs without external LNAs, while ±0.19 dB amplitude accuracy keeps compliance results tight. SCPI/LAN automation, 16 measurement personalities, and option-upgrade paths extend utility.

Refurbished units ship quickly with fresh ISO-17025 calibration and verified firmware, cutting capital cost and lead-time yet retaining Agilent reliability and long-term serviceability.
